Unable to launch WebDriverAgent because of xcodebuild failure: xcodebuild failed with code 70

I am trying to launch an iOS app with Appium on Simulator.

Appium : Version 1.17.1

Xcode : Version 1.14

Mac : 10.15.5

Simulator: iPhone Pro

iOS Version: 13.0

When I start my automation test, I get this error in few moments:

An unknown server-side error occurred while processing the command. Original error: Unable to launch WebDriverAgent because of xcodebuild failure: xcodebuild failed with code 70 xcodebuild error message:
(Selenium::WebDriver::Error::UnknownError) UnknownError: An unknown server-side error occurred while processing the command. Original error: Unable to launch WebDriverAgent because of xcodebuild failure: xcodebuild failed with code 70

Any idea to solve the problem?

Issue solved.
Check whether an instance of simulator is targeting a different iOS version.
